The effects of mutual coupling between antenna elements of the performance adaptive arrays Özkaya, Güney; Alatan, Lale; Department of Electrical and Electronics Engineering (2003) Array processing involves manipulation of signals induced on various antenna elements. In an adaptive array system, the radiation pattern is formed according to the signal environment by using signal processing techniques. Adaptive arrays improve the capacity of mobile communication systems by placing nulls in the direction of interfering sources and by directing independent beams toward various users. Adaptive beamforming algorithms process signals induced on each array element that are assumed not to be a...
Direction finding performance of antenna arrays on complex platforms using numerical electromagnetic simulation tools Özeç, Mustafa Onur; Tuncer, Temel Engin; Department of Electrical and Electronics Engineering (2011) An important step for the design of direction finding systems is the performance evaluation using numeric electromagnetic simulation tools. In this thesis, a method is presented for both modeling and simulation in a numeric electromagnetic simulation tool FEKO. The method relies on the data generated by FEKO. The data is then processed by correlative interferometer algorithm. This process is implemented in a MATLAB environment. Different types of antenna arrays including dipole, monopole and discone antenna...
Anten Uygulamalari için Yeni MEMS Anahtar Yapiları Ünlü, Mehmet; Sağkol, Hüseyin; Topallı, Kaan; Aydın Çivi, Hatice Özlem; Demir, Şimşek; Koç, Seyit Sencer; Akın, Tayfun (2002-09-18) Bu bildiride Mikro Elektro Mekanik Sistemler (MEMS) teknolojisi kullanılarak üretilmiş iki RF anahtar sunulmaktadır. Bu anahtarlar özellikle fazla sayıda anahtar gerektiren MEMS faz kaydırıcı ve faz dizili anten gibi uygulamalara yönelik tasarlanmışlardır. Yapılardan birincisi eşdüzlemli dalga kılavuzu üzerinde paralel anahtarlama yapan “T-kanatlı” anahtardır ve yapılan benzetimlerle araya sokma yitimi, 10 GHz frekansında -0.035 dB, yalıtımı ise -33 dB olarak belirlenmiştir. Diğer yapı eşdüzlemli dalga kıla...
MMSE based iterative turbo equalization for antenna switching sytems Yıldırım, Recep Ali; Yılmaz, Ali Özgür; Department of Electrical and Electronics Engineering (2010) In this thesis, we study the performance of an antenna switching (AS) system in comparison to an Alamouti coded system. We analyze the outage probabilities and propose minimum mean-squared error based iterative equalizers for both systems. We see from the outage probability analysis of both systems that the AS system may achieve the same diversity order of the Alamouti coded scheme contingent on the transmission rate and constellation size. In the proposed receiver, MMSE equalization and channel decoding ar...
The electrical characteristics of antennas in their operational environment Afacan, Gönenç; Tuncay, Birand; Department of Electrical and Electronics Engineering (2007) This thesis investigates the variations of electrical properties of linear antennas mounted on certain platforms, depending on the physical properties of that platform. In this respect, related basic antenna simulations, electromagnetic simulations from primitive to complex models of airframes, and scale model measurements were used. Firstly, electrical properties of monopoles at known environment were examined and basic analyses were performed via an electromagnetic simulation tool, named CST Microwave Stu...
